INTERCHANGEABLE HEEL.

SPECIFICATION forming part of Letters Patent No. 487,312, dated December6, 1892.

Application iiled August 20,1891. Renewed June 8. 1892. Serial No.435,943. (No model.)

To all whom t may concern.-

Be it known that I, MORRIS VISE, a citizen of the United States,residing at New York, in the county and State of New York, have inventednew and useful Improvements in Interchangeable Heels, of which thefollowing is a specification.

This invention relates to an improvement in heels for boots and shoes;and the invention consists inthe novel features ofconstructionhereinafter described and claimed for making the heels interchangeableor readily removable and attachabie, so that when a heel is worn orinjured or the style of heel is to be changed the heel in the boot orshoe can be readily removed and another substituted.

Thisinvention is illustrated in the annexed drawings, in which- Figurelis an inverted plan View nf a sole adapted to receive a heel. Fig. 2 isa plan View of a heel adapted to be secured to the sole shown in Fig. l.Fig. 3 is a detail view of a key. Fig. 4 shows the key applied to use.Fig. 5 is a section along 00x, Fig. 4. Fig.

6 is a section along y y, Fig. 4.. Fig. 7 is an inverted plan View of asole with a modified form of attaching device. Fig. 8 is a plan view ofa heel adapted to be secured to the sole shown in Fig. 7. Fig. 9 shows akey adapted for use with the heel of Fig. 8. Fig. 10 shows Athe key ofFig. 9 applied to use. Fig. 11 is a section along z e', Fig. 10. Fig. 12is a section along w w, Fig. 10. Fig. 13 is a longitudinal section of amodification.

In the drawings, the letter A indicates the sole to which the heel is tobe attached, and B is the heel. 'lo the sole is secu red a plate O,having eyes D, and the heel is provided with a plate E, having eyes F.When the heel is placed in position, the eyes D F are in alignment, andby inserting the key G in place, so as to engage the eyes D F, the heelis secured in place. The key G has an eye H, into which can be insertedan awl, hook,

or other suitable tool for withdrawing the key when the heel is to beremoved. In order that the position of the heel can be easily fixed,pegs or projections I, engaging suitable eyes or depressions K, can beprovided, and by means of these pegs the key G is also relieved fromconsiderable lateral strain. while the wearer is walking.

In Figs. 7 to 12 the plates O E are shown as having each a double row ofeyes D F, and the key G, Fig. 9. has two branches for engaging saideye-rows.

The key in Figs. 1 to 12 is inserted and withdrawn at the back; but bymaking the channel or passage for the key extend from the back throughthe breast of the heel, as seen in Fig. ]3,`the key can be passed intoplace at the back and then pushed through and withdrawn at the breast,or vice versa.

The heel can be attached to the sole or quarter, as in Figs. 1 to l2, ora lift L can be secured to the sole or quarter, as in Fig. 13, and theheel B attached to this lift.

What I claim as new, and desire to secure by Letters Patent, is

The sole A, having the attached plate O struck up with the series ofoutwardly-projecting eyes D, in combination with the heel B, having theattached plate E arranged on its upper surface and provided with theseries of struck-up eyes F, which pass between the eyes of thesole-plate, and the lengthwisesliding key G, composed of a flatrectangular plate inserted through the struck-up eyes of the two plates,substantially as shown and described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
